BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel used for a shed structure and a shed structure, and more specifically, a multi-story shed having two layers, an upper layer and a lower layer, which are excellent in heat insulation and airtightness. The present invention relates to a panel and a roof frame structure using the panel.

[0002]

2. Description of the Related Art In the conventional roof structure of a wooden house, a field board is nailed on a rafter, a waterproof layer such as asphalt felt is laminated thereon, and a roof such as a tile is further formed on the roof. Thatching was done.

[0003]

However, in the above-mentioned conventional shed construction structure, although the waterproof material is interposed between the base plate and the roofing material, neither the moisture-proof material nor the heat-insulating material is provided in the back of the shed. Often not used. As a result, there are issues such as high temperature hot air in the summer that heats the living room to the living room, and in the winter it cools down, and there is a problem that moisture condenses to moisten the attic. However, it was only used as a storeroom at best, and it was not considered to be used as a living space. In addition, in order to avoid the propagation of hot air from the back of the hut, an insulating material may be laid on the ceiling below the hut, but even in this case, the hut cannot be used as a living space. There were challenges.

Further, in recent years, in the construction of wooden houses,
House construction using panels is often adopted in order to cope with soaring labor costs and the shortage of technicians, and for the purpose of shortening the construction period and lowering costs, etc. The precedent used is unknown. The present invention has been made in view of the above-mentioned problems of the conventional technology, and an object thereof is to achieve high airtightness and high heat insulation of a house, and to quickly construct a rooftop structure, and (EN) It is intended to provide a multi-story shed panel capable of expanding a living space and a shed assembly structure using the same.

[0005]

In order to achieve the above-mentioned object, the multi-story shed panel of the present invention is used in a shed construction structure composed of two layers of panels, an upper panel on the side of a main plate and a lower panel on the indoor side. In the panel, the upper layer panel has a built-in heat insulating material, and a plywood is stretched on the upper surface of the frame member, and a heat insulating material sheet is stretched on the lower surface. It is characterized in that it is built-in and is constructed by stretching plywood on both sides of the frame member. Further, the shed construction structure of the present invention is a shed construction structure of a wooden house, in which a door member is installed in a gap between a floor beam and a climbing beam provided with a panel support portion and a panel stopper, and between the climbing beams, It is characterized by arranging multi-story hut panels.

[0006]

The hut panel of the present invention is composed of two layers of heat insulating panels, an upper layer and a lower layer, in which a heat insulating material is enclosed. A moisture-proof sheet is stretched (attached) on the lower surface of the upper layer panel, which can improve not only the heat insulating property but also the airtightness of the house. Therefore, the use of the airtight material can be omitted. On the other hand, it is preferable that the lower layer panel is formed so that the thickness of the panel itself is slightly thin. Further, by strengthening the nailing around the beam, the struck beam can be omitted, and further, if a decorative plywood is stretched on the lower surface, ceiling finishing is not necessary. As described above, the heat insulating property and the airtight property of the upper layer panel and the strength, the heat insulating property and the cosmetic property of the lower layer panel are combined, so that the composite effect of the multiple layers can be enhanced. As described above, the multi-story shed panel of the present invention has two independent heat insulation layers, and has high airtightness, so that it has excellent heat insulation properties, and has heat intrusion from the outside and heat dissipation to the outside. Can be effectively prevented.

Further, in the shed construction structure of the present invention, it is sufficient to fit the above-mentioned multi-story shed panel between the panel support portions of the climbing beam, and it is possible to improve the size and positioning accuracy and shorten the working time. .. Further, the ground board may be placed on the upper surface of the upper panel, and the scaffolding is stable, so that it can be performed quickly and the safety of the worker can be improved.
